A solution of CuSO4 was kept in an iron pot.


A solution of CuSO4 was kept in an iron pot. After few days, the iron pot was found to have a number of holes in it. Explain the reason in terms of

reactivity. Write the equation of the reaction involved.


Iron (Fe) is placed above copper (Cu) in the reactivity series. This means that a chemical reaction had occurred between iron (iron pot) and aqueous

CuSO4 solution.

$\mathrm{Fe}(s)+\mathrm{CuSO}_{4}(a q) \longrightarrow \mathrm{FeSO}_{4}(a q)+\mathrm{Cu}(s)$

Since iron was consumed in the reaction, a number of holes appeared in the pot.
